Buy any BG items with points

[GM-Ciar]

Personally, I'm fine with de-classing(?) the BG shop and allowing odd number of total players to participate. It'd help increase BG activity and take away some of the pains of fighting on certain classes (IE, 1 HP and a Linker vs 1 HP and and a Clown).

Changing the BG point variable to account bound might be a bit trickier since it's been around as character bound for quite some time, but can/should still be done.
